Get Brenda to blow Max

"Brenda could you please suck your brother's dick?"

"WHAT?! MOM!"

"Don't make a scene, just... I'm the only one bringing money into this family right now and it keeps getting spent on mods and sex."

"I regret nothing!" shouted Max as he stuffed his face back into his mother's bare chest.

Chelsea looked over her son's head and continued pleading with her daughter. "Please, dear. We just can't afford to keep wasting money like this. It's legal here...normal even. We already let Max touch us. Think of it like you're touching him... With your mouth."

"No! That's gross!"

Chelsea wasn't done arguing. She grabbed her daughter's chin and thrust her fingers into her mouth. Brenda started moaning uncontrollably due to her mouth's new sensitivity.

"Doesn't this feel nice, Brenda? Help your family now and your brother could make you feel this good anytime you want."

"Anytime he wants," snickered Justin.

"Mmph, o-ay! I'll 'oo it! Please s'op! ... You'll make me 'um!"

Chelsea slid her fingers out of her daughter's mouth and wiped them on Brenda's face, since it was just going to get messier anyway...

Melissa frowned. She knew her opportunity to up-sell to the Alpha was gone when Max grabbed Brenda's head and pushed it down onto his cock.

"Fuck yeah, sis. Your mouth is so hot! Thanks, mom. You're right, I should do this every day!"

Chelsea hesitated as she watched her son treat her daughter's throat like a cheap toy. "N-No, that's not what I meant... This is just because..."

"Shh. Don't care. Rub your tits in my face. I've had enough to eat. It's time to give Brenda her dessert."

"Yes, dear... Um, is this ok? Would you ... like to suck on my nipples?"

At this point Libby and Justin were chatting between themselves, paying no attention to the incestuous acts taking place right next to them. Libby was wonderfully happy with her new body and was telling Justin all about her newfound confidence. Every morning when she went for a run she would wave to the neighbours. One young Alpha was particularly taken with her. He'd wait on his front lawn with an older woman stroking his dick - likely his mother. And when Libby ran by he'd shove his mom's head onto his cock and fuck her face till he came, all the while staring at Libby jogging by.

Justin had never known his sister to talk about guys being interested in her before. Brenda, sure, but not Libby. He was happy for her. He'd been worried that their newly morphed bodies would make it hard to attract partners of their own, but he'd been pleasantly surprised as well. He'd achieved a new measure of popularity at high school. Especially with the girls who were into K-Pop and boy bands. Girly guys were in. His strength mods had helped as well. Even though he was still very svelte, the bullies wouldn't dare go near him. One of them had tried, but they learned their lesson pretty quick.

He had to pause a few times while he chatted with Libby; Brenda kept making these annoying gagging noises while her throat was being abused.

"I'm happy for you too," said Libby. "Even I've been thinking how much more attractive you've become. You really pull off this new look!"

"Aw, thank you sis!" he giggled.

Evening turned to night and the family chatted over dessert. When they were all finally done and the bill was paid, Max reluctantly disentangled himself from his mother and older sister. Chelsea delicately rolled down her top; her breasts were sore after being manhandled for so long. But that was nothing compared to what Brenda had been through. Max had fucked her face through dessert and the long, long wait for the bill. His enhanced Alpha cock and balls had pumped load after load down her gullet. And due to her sensitivity enhancements, she orgasmed each time Max blasted her throat with jizz. When they got up from the table her stomach had more cum than food inside of it. She clutched her swollen belly and burped. Her breath didn't smell like Mexican food, she smelled like a sex toy.

And as far as Max was concerned, that's what she and her mother had become.
